Integral equations of a cohesive zone model for history-dependent materials and their numerical solution [PDF]
, 2014 A nonlinear history-dependent cohesive zone (CZ) model of quasi-static crack propagation in linear elastic and viscoelastic materials is presented. The viscoelasticity is described by a linear Volterra integral operator in time.

Fatigue crack propagation in microcapsule toughened epoxy [PDF]
, 2004 The addition of liquid-filled urea-formaldehyde (UF) microcapsules to an epoxy matrix leads to significant reduction in fatigue crack growth rate and corresponding increase in fatigue life.

Crack propagation in viscoelastic solids [PDF]
Physical Review E, 2005 We study crack propagation in a viscoelastic solid. Using simple arguments, we derive equations for the velocity dependence of the crack-tip radius, a (v) , and for the energy per unit area to propagate the crack, G (v) . For a viscoelastic modulus E (omega) which increases as omega(1-s) (0< s< 1) in the transition region between the rubbery region and

Local dynamics of a randomly pinned crack front during creep and forced propagation: An experimental study [PDF]
, 2011 We have studied the propagation of a crack front along the heterogeneous weak plane of a transparent poly(methyl methacrylate) (PMMA) block using two different loading conditions: imposed constant velocity and creep relaxation.

Numerical investigation on the prefabricated crack propagation of FV520B stainless steel
Results in Physics, 2017 FV520B is a common stainless steel for manufacturing centrifugal compressor impeller and shaft. The internal metal flaw destroys the continuity of the material matrix, resulting in the crack propagation fracture of the component, which seriously reduces ...

Advances in Mechanical Engineering, 2019 To overcome the limitation of constant Poisson’s ratio in bond-based peridynamics, an ordinary state-based peridynamic (OSB PD) model was applied to simulate dynamic crack propagation in Kalthoff–Winkler specimen subjected to a low velocity impact.
